According to the British Daily Mail, a revolution in lighting is quietly underway, and traditional bulbs and energy-saving light bulbs will compete fiercely. At present, researchers at the University of Cambridge in the United Kingdom have developed an inexpensive light-emitting diode (LED) bulb that can emit bright light with less power. Its price is only 2 pounds, sustainable use 60 years.
British scientists newly developed light-emitting diodes
Although this LED bulb is also small, it is 12 times more luminous than traditional tungsten bulbs and 3 times fluorescent light bulbs. It is different from current energy-saving light bulbs that can be fully illuminated directly after power is turned on. The British Engineering and Physical Science Research Council believes that the use of new LED light bulbs will reduce three quarters of home lighting power consumption. If such bulbs are installed in every home and office, the annual lighting consumption will reduce from 20% of the total power consumption to 5%.
In early January of this year, the British "Daily Mail" reported that people began to pay attention to the use of energy-saving light bulbs, and many stores stopped stocking traditional 100-watt incandescent bulbs. This has caused panic buying by many consumers. The British government said that the use of energy-saving light bulbs can reduce the release of 5 million tons of carbon dioxide per year.
They used an artificial semiconductor material, niobium nitride, in LED bulbs to make light-emitting diodes. Due to the advantages of inexpensive LED size and brightness compared to conventional light bulbs, it has been used to make bicycle lights, cell phone lights, camera flashes, and the like.
However, the current manufacturing cost of light emitting diodes is too expensive to use if widely used. This is because the materials for manufacturing light emitting diodes must be derived from “sapphire wafers,†which means that the cost of producing light emitting diode light bulbs will be high, about 20 GBP. At present, scientists from the Nitrate-Nitrogen Research Center of the University of Cambridge in the United Kingdom have proposed an effective solution. They will use silicon wafers to manufacture light-emitting diodes, which will greatly reduce the cost. The RFMD company in Durham County, United Kingdom, has begun work on the prototype of this product and it is expected that the first LED bulb will be sold on the market within two years.
